Check the fuse box for a blown rear wiper fuse and verify the 3-pin connector is securely clicked into place.
Ensure the wiper arm nut is tightened correctly and the spindle is free of corrosion; also check the blade for excessive friction against the glass.
Verify that the motor is correctly aligned in the tailgate and that the wiper arm is not bent or obstructed.
To install, you will need to access the interior of the tailgate by removing the plastic trim panel. Disconnect the negative battery terminal before handling any electrical components to prevent short circuits. Remove the external wiper arm, unscrew the retaining bolts from the old motor, unplug the 3-pin connector, and reverse the process with the new unit. Ensure the motor is properly seated against the rubber seal on the exterior of the glass to prevent water ingress. Regularly inspect the wiper blade for wear, as a damaged blade can put unnecessary strain on the motor mechanism, potentially shortening its lifespan.
